💙 Project Blue Tent – Week 6
Blue Waffle F1 – Pheno B (Folder 13B)
Hello everyone, and welcome back to another chapter of Project Blue Tent.
If you're joining the adventure for the first time, welcome! This project follows four individual Blue Waffle F1 plants from Zamnesia, all growing inside exactly the same environment, under the same lighting, receiving the same nutrition and following the same training schedule.
Everything is identical.
The only difference is the seed itself.
That's what makes this project so interesting. Watching genetically stable F1 plants develop their own subtle personalities while removing as many environmental variables as possible allows us to really appreciate both their consistency and their individuality.
Today we're checking in with Plant B.

🌱 Week Six – Building the Canopy
Another fantastic week has passed inside the Blue Tent, and Plant B continues proving why I'm becoming such a fan of these Blue Waffle F1 genetics.
After installing the SCROG net last week, the objective has completely changed.
We're no longer trying to grow taller plants.
Now we're growing sideways.
Since tightening the SCROG net, all four plants are sitting at roughly the same height—around 60 cm—as the branches are continuously guided beneath the screen instead of being allowed to grow vertically.
Every day I spend a few minutes gently tucking the tallest branches back underneath the net. As soon as one shoot rises above the canopy, it's carefully guided into the next square, allowing another branch to catch up.
It's a slow process.
But it's also one of the most satisfying parts of growing.
The reward comes later, when every flowering site receives nearly identical light intensity across the entire canopy.
Plant B has responded beautifully.
She's steadily filling her section of the tent and showing exactly the kind of structure I was hoping for.

🌿 A Stable F1 Showing Her Strength
One thing becoming increasingly obvious is just how stable these F1 genetics really are.
Although each plant has its own small personality, all four sisters are developing remarkably similarly.
The structure...
The vigour...
The colour...
The response to feeding...
Everything is wonderfully consistent.
Plant B has maintained her compact, organised architecture while expanding nicely across the screen.
The rich green colour has fully returned after increasing the nutrient strength a couple of weeks ago, and the new growth is healthy, vibrant and full of energy.
Looking across the tent now, it's honestly difficult not to smile.
The girls simply look happy.

🌡️ Blue Tent Environment
The environment has remained very stable once again despite the summer heat outside.
This week's average conditions were:
• Day Temperature: 30°C
• Night Temperature: 25°C
• Relative Humidity: 58%
• pH: 5.8
• EC: 1.92 mS/cm
• CO₂: approximately 450 ppm
• Light Schedule: 18/6
• Irrigation: 1.2 litres per plant per day
The warm nights are something I'll be keeping an eye on once flowering begins, as higher night temperatures can encourage a little extra stretch during the first weeks after the flip.
That's tomorrow's problem though.
Today our only objective is filling every square of that SCROG.
────────────────────────
🥥 Feeding & Irrigation
Nothing changes this week because the plants have given me absolutely no reason to change anything.
The feeding schedule remains:
• Plagron Hydro A — 1.9 ml/L
• Plagron Hydro B — 1.9 ml/L
• Plagron Hydro Roots — 1 ml/L
With only small pH adjustments whenever required.
Some growers may look at an EC of 1.92 and think it's relatively high.
My plants disagree.
Their colour is rich.
The leaves are praying.
Growth is vigorous.
The stems continue thickening every day.
Plants don't care what feeding chart someone else follows.
They care whether their own needs are being met.
These girls have made their opinion very clear.
────────────────────────
💧 Drip Irrigation & Automatic Drainage
The Mars Hydro drip irrigation system continues making life wonderfully easy.
Each plant receives approximately 1.2 litres of nutrient solution every day, delivered slowly and evenly through individual drippers positioned above each grow bag.
Once the nutrient solution has passed through the coco, the runoff is automatically collected and removed by the drainage system installed beneath the pots.
Together these two systems create an incredibly consistent root environment while removing much of the daily workload that normally comes with coco growing.
Instead of carrying watering cans...
I get to spend my time watching plants.
That's a trade I'll happily make every day.

🐛 The Caterpillar Who Chose The Wrong Plant
Every garden eventually reminds us that nature always finds a way.
This week, Plant B became the only sister to receive an unexpected visitor.
Somehow a tiny caterpillar managed to hitchhike its way from my vegetable garden into the Blue Tent and decided that Plant B's beautiful leaves looked particularly delicious.
I have to admit...
She must have looked especially healthy if even the caterpillar couldn't resist having a taste!
Fortunately, regular daily inspections meant the damage was caught almost immediately.
The caterpillar was removed by hand, the affected leaves were carefully trimmed away, and the problem never had an opportunity to develop into anything more serious.
It also served as a perfect reminder that no matter how careful we are—and I always shower, change clothes and enter the grow room as clean as possible—nature can still surprise us from time to time.
Clean habits reduce risk.
Regular observation eliminates it.
────────────────────────
🛡️ Integrated Pest Management
Following the discovery, the entire tent received a thorough IPM (Integrated Pest Management) inspection.
IPM isn't about waiting until pests become a problem.
It's about combining good hygiene, regular inspections and preventative practices so problems are found while they're still tiny.
As an additional precaution, I also used the Future of Grow UVC LED bar.
Used correctly, UVC light can help reduce unwanted spores and microorganisms that may have entered the grow room, making it another useful preventative tool within an overall IPM strategy.
It's important to mention that UVC should always be handled carefully.
Direct exposure can damage both plants and skin, so eye protection and proper safety procedures are essential whenever using this type of equipment.
Thankfully...
One hungry caterpillar became nothing more than a short interruption to an otherwise fantastic week.
────────────────────────
🌿 Plant B Herself
Plant B continues becoming one of the easiest plants to train inside the tent.
Her branches remain flexible, her internodal spacing is excellent and she seems perfectly happy being guided beneath the SCROG every single day.
She's not racing ahead.
She's building a beautifully organised framework that should become an outstanding flowering canopy once the time comes.
Every week she seems a little fuller.
Every week she looks a little stronger.
And every week these Blue Waffle genetics impress me a little more.
────────────────────────
👀 Looking Ahead
If everything continues progressing at this pace, I expect the screen to be almost completely filled by next week.
Once that happens, the next major milestone will be a final clean-up and defoliation before flipping the Blue Tent into flower.
Until then the routine stays wonderfully simple.
Guide the branches.
Maintain the environment.
Keep the roots happy.
Trust the process.
Nature already knows what she's doing.
We're simply helping her do it a little more efficiently.

💙 Thank You
A huge thank you to Zamnesia for making Project Blue Tent possible, from these incredibly stable Blue Waffle F1 genetics to the complete ecosystem surrounding this grow.
A heartfelt thank you to Plagron for providing the Premium Coco Growbags together with the Hydro nutrient line that continues producing beautiful, healthy growth week after week.
A special thank you to Mars Hydro for the automatic drip irrigation and drainage system that has transformed daily watering into an almost effortless routine.
A huge thank you as well to Future of Grow for the UVC LED bar, which has now become another valuable tool in my preventative IPM routine.
Thank you to GrowDiaries for providing this amazing platform where growers from around the world can learn from one another, share experiences and document our journeys.
And finally...
Thank you to every single one of you following Project Blue Tent.
Whether you've been here since germination, recently joined the adventure, leave comments every week or simply enjoy looking through the photos, your support genuinely means the world to me.
Hopefully next week the screen will be completely filled, we'll perform our final defoliation and begin preparing these beautiful ladies for the next exciting chapter...
Flowering.
Until next week...
Growers Love, happy growing, and I'll see you all soon. 🌱💙
